2018 Isuzu D-Max Concept X Dimensions, Size & Specs

The Isuzu D-Max Concept X boasts an impressive ride height with a ground clearance of 370 millimeters (14.6 inches), which is substantially higher than many conventional pickup trucks and off-road vehicles. This elevated ground clearance is critical for off-road capability, as it allows the vehicle to traverse rough terrains, rocks, deep ruts, and obstacles without damaging the underbody or getting stuck. It enhances the truck's approach, breakover, and departure angles, making it more versatile for extreme off-road conditions.

The Isuzu D-Max Concept X prototype is equipped with massive 12J x 20 rims and oversized tires measuring 38/15.5 R20. These dimensions are considerably larger than standard stock pickup wheels and tires. The large 20-inch rims combined with wide, tall tires improve traction on loose or uneven surfaces such as mud, sand, and rocks. Additionally, the tall 38-inch tires increase ground clearance, further enhancing off-road capability by reducing the chance of bottoming out. Overall, these tire and rim specs are integral to the Concept X's intended rugged, trail-focused performance.

Given its substantial dimensions—5500 mm (216.5 inches) in length, 2150 mm (84.6 inches) in width, and a tall height of 2100 mm (82.7 inches)—the Isuzu D-Max Concept X would generally be too large for most standard residential garages. Typical single-car garages measure roughly 6000 mm (20 feet) deep by 3000 mm (10 feet) wide, so while the length might be manageable, the width and height could pose clearance challenges. Additionally, the wide mirrors and oversized tires exacerbate space concerns. Therefore, most owners would likely require a specialized parking space or oversized garage to accommodate this pickup comfortably.

Compared to previous generation Isuzu D-Max pickups, the Concept X is markedly larger in every key dimension. Earlier D-Max models generally fall closer to 5200 mm (204.7 inches) in length and around 1800-1900 mm (70.9-74.8 inches) in width, making the Concept X substantially longer and wider by several hundred millimeters. The height of 2100 mm (82.7 inches) also greatly exceeds the typical D-Max range of approximately 1795-1800 mm (70.7-70.9 inches). This increase showcases the Concept X's conceptual emphasis on off-road prowess and presence, giving it a much more commanding footprint than its production predecessors.

When compared to off-road rivals such as the Ford Raptor or Toyota Hilux, the Isuzu D-Max Concept X prototype is noticeably larger, especially in length, width, and ground clearance. For example, the Ford Raptor is approximately 5630 mm (222 inches) long and 2180 mm (85.8 inches) wide but typically features less extreme ground clearance around 280 mm (11 inches). The Toyota Hilux is smaller still, roughly 5330 mm (210 inches) in length. The Concept X’s massive 2150 mm (84.6 inches) width and 370 mm (14.6 inches) ground clearance set it apart with a more extreme off-road-oriented design, suggesting a specialized niche above most traditional pickups.

The Isuzu D-Max Concept X features a substantial ride height with a ground clearance of 370 millimeters (14.6 inches). Such a high ground clearance is advantageous for maneuvering over obstacles like rocks, logs, and uneven terrain often encountered in off-road environments. It prevents the undercarriage from scraping or getting stuck, thus improving durability and mobility. It also enhances the vehicle's ability to handle water crossings and rough paths by keeping vital components elevated above potential hazards.

The 38/15.5 R20 tires on the Isuzu D-Max Concept X prototype are exceptionally large and wide, designed specifically to maximize traction and stability in off-road settings. The 38-inch diameter (approximately 965 mm) provides substantial ground clearance, aiding in obstacle navigation. The 15.5-inch width (around 394 mm) means a larger contact patch on the ground resulting in better grip on loose surfaces such as mud, sand, or snow. Mounted on 20-inch rims, these tires contribute to the Concept X’s aggressive and capable character, as oversized tires are standard for serious off-road and rock crawling applications.

The Isuzu D-Max Concept X is a prototype or concept vehicle produced between 2018 and 2020. It was never intended for mass production but served as a design and capability showcase highlighting potential future directions for the D-Max lineup. The Concept X emphasized extreme off-road performance, bold styling, and large-scale enhancements such as oversized tires and increased ground clearance. Concept vehicles like this are typically used by manufacturers to gauge public and media reaction to new ideas and styling cues before committing to production versions.

With a width of 2150 millimeters (84.6 inches), the Isuzu D-Max Concept X is considerably wider than typical pickup trucks. This width offers excellent stability and a commanding road presence, especially off-road, but it can pose challenges in urban settings. Maneuvering on narrow city streets, fitting into standard parking spots, or navigating tight spaces can be difficult. Drivers will need to be cautious of curbside obstacles and other vehicles, and may require specially sized parking areas due to the Concept X's outsized footprint.
